Add a CLI under frontend/performance/benches/render_wasm that builds the
renderer, runs seeded scenes (rects, plus, paths, masks) in headless
Chromium and saves per-case timings.
- build, run: prepare or reuse builds; measure cases with warmups,
repetitions, deadlines
- ab: build and compare Cargo feature configurations
- compare, merge: median changes with bootstrap CIs between saved runs,
guarded by scene, build and settings checks
- purge: delete managed builds, runs or comparisons
- GPU runs through `run-devenv --gpu`
Lint, format and pnpm scripts now cover performance/ and its tests.

Forward Cargo arguments as an array and honor explicit profiles.
Build and copy each renderer target once under the repository lock,
with watch rebuilds using the same wrapper.
Select this checkout's compiler artifact and matching generated enum
table from Cargo JSON. Record actual features, profile and output paths,
and allow callers to override publication destinations.
Run the existing Cargo parser tests before the renderer's native tests
and stop on parser failures.
